The fully suppressed model is a fun toy but I think myself the Buckmark is of better construct. Buckmark LBPs are available here as quite a few were converted from the carbine model.
We may see single shot .22LRs back at most but I would be extremely surprised if it did come to pass. One of the top responses to athletes getting them on temporary license was ("it's a risk to public safety"), so I doubt us mere mortals would be allowed to handle one. We'll be lucky if the 2012 pistol comps aren't held behind bullet-proof glass with optional blindfolds and earplugs to protect more timid spectators from the fear and evil emanating from the unwieldy lumps of target pistols.
